〔産業上の利用分野〕
本発明は、道路の状況に対応して操縦安定性が確保でき
、しかも美観向上しうるタイヤ用のリムに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tire rim that can ensure steering stability in response to road conditions and can also improve aesthetic appearance.
自動車用タイヤ及びそのタイヤが装着されるリムは、様
々な道路状態及びドライバーの運転の仕方を配慮し、こ
れ等の平均値的な条件を基本として定められる。Automobile tires and the rims on which they are mounted are determined based on average values of these conditions, taking into account various road conditions and the driving style of drivers.
しかし前記タイヤとリムとの組合わせでは、例えば四輪
駆動車などによるコーナの多い山路の走行、厳しいコー
ナリング走行時にはタイヤの横剛性が不足し、操縦安定
性に欠ける場合が多々ある。However, with the combination of the tire and rim, the lateral rigidity of the tire is often insufficient when a four-wheel drive vehicle is traveling on a mountain road with many corners or when driving through severe cornering, resulting in a lack of steering stability.
このような道路条件に対応して操縦安定性を確保するに
は、タイヤとリムとをその都度取替えることが考えられ
るが、タイヤおよびリムの管理が複雑となり又費用も嵩
む。In order to ensure steering stability in response to such road conditions, it is conceivable to replace tires and rims each time, but this would complicate the management of tires and rims and increase costs.
他方、車両の美観を向上するためにサイドウオール部を
カラフルに仕上げたタイヤも存在するが、近年資源節約
の観点から自粛気味であり、入手が困難な状況になって
いるため、タイヤ以外の面で美観向上させる要望が特に
若年層のドライバーから高まっている。On the other hand, there are tires with colorfully finished sidewalls to improve the aesthetics of the vehicle, but in recent years there has been a tendency to refrain from doing so in order to save resources, and it has become difficult to obtain them. There is a growing demand for improved aesthetics, especially among young drivers.

連続するリング体とからなる。In order to solve the above-mentioned problems, the tire rim of the present invention includes a rim body and a flange of the rim body, which is screwed to the outside of the flange, and is in contact with the outer surface of the sidewall portion of the tire mounted on the rim in the radial direction. It consists of a ring body that extends outward and is continuous in the circumferential direction.
又、リング体は、リム本体のビードシート面からリング
体の外端側までの高さであるリング高さ（Ｈ１）がリム
本体に装着された標準タイヤの前記ビードシート面から
のタイヤ高さ（Ｈ２）の０゜３倍以上かつ０．６倍以下
であることが望ましい。The ring height (H1), which is the height from the bead seat surface of the rim body to the outer end of the ring body, is the same as the tire height from the bead seat surface of a standard tire mounted on the rim body. It is desirable that it is 0°3 times or more and 0.6 times or less of (H2).
〔作用〕
リング体は、タイヤのサイドウオール部の外面に接触し
